Currently the lmce_game database stores simple attribute metadata for a series of ROMs using a schema pattern similar to pluto_media where the central tables are Rom, RomAttribute, and Rom_RomAttribute, creating essentially a Has and Belongs to many Pattern (HABTM)

The psc_ tables were created by sqlCVS when I told it to create a new repository in the database to hold history data. same for any psc_tables in the database, lmce_game_update is unaware of them, and does not touch them at all.
